Abstract
The utility model relates to a horizontal boiler smoke box for double sealed construction, belonging to the heat-production device art field. The utility model comprises a casing (2), a smoke box door (3), a baffle plate (6), a graphite asbestos ribbon (7), a graphite asbestos square packing (8), a band steel (9), a quadrant iron (10), a bolt (11) and a contact flange (12). The doorway of the casing (2) is provided with two stage step surfaces including an internal stage step surface and an external stage step surface, wherein the first stage step surface is the baffle plate (6), the graphite asbestos ribbon (7) is fixed on the outside of the baffle plate (6), the second stage step surface is the contact flange (12), the graphite asbestos square packing (8) is fixed on the outside of the contact flange (12), the smoke box door (3) is hinged in the doorway of the casing (2) relative to the second stage step surface arranged in the doorway of the casing (2). The inward portion of the inner center of the smoke box door (3) is provided with a boss(13), the inside of the smoke box door (3) is also arranged with two stage step surfaces including an internal stage step surface and an external stage step surface, wherein the first stage step surface is the top surface of the boss(13), the second stage step surface is the inside edge of the smoke box door (3). The quadrant iron (10) projected inward is arranged at the inside edge of the smoke box door (3) relative to the graphite asbestos square packing (8). The utility model has the advantages of good sealing property.
Description
Technical field:
The utility model relates to a kind of boiler.Be specifically related to a kind of horizontal boiler smoke box of double sealing structure.Belong to the heating equipment technical field.
Background technology:
Smoke box is loaded on the forward and backward of boiler body, is used for converging and turning back of flue gas, and can open smoke box door and the weld seam of smoke pipe, smoke pipe and tube sheet is overhauled and safeguard.Horizontal fuel oil in the past, the forward and backward smoke box of gas fired-boiler; its casing only adopts the sealing surface sealing between smoke box door; and fuel oil, gas fired-boiler are generally operation under the pressure-fired high temperature, and the leakage accident through flue gas takes place in regular meeting influences the normal operation of equipment when serious.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of horizontal boiler smoke box of double sealing structure of good airproof performance is provided.
The purpose of this utility model is achieved in that a kind of horizontal boiler smoke box of double sealing structure, comprises casing, smoke box door, dividing plate, graphite asbestos yarn, graphite asbestos packing, band steel, square steel, bolt and adpting flange,
Described casing doorway is provided with inside and outside two stage steps face, and first order step surface is a dividing plate, and the graphite asbestos yarn is fixed on the dividing plate outside, and second level step surface is an adpting flange, and the graphite asbestos packing is fixed on the adpting flange outside,
Described smoke box door is hinged on the casing doorway, two stage steps face corresponding to the setting of casing doorway, the inboard center of smoke box door is to the projecting inward boss that is provided with, make the smoke box door inboard also be provided with inside and outside two stage steps face, first order step surface is the boss top end face, second level step surface is the smoke box door inside edge, and square steel is to the projecting inward smoke box door inside edge that is arranged at, and its installation site is corresponding with the graphite asbestos packing on the step of the second level, casing doorway.
Boiler in normal operation, smoke box door is connected by bolt with casing and is fixing, because the thrust of bolt, inboard boss of smoke box door and graphite asbestos yarn compress and form the first road sealing surface, square steel and graphite asbestos packing compress and form the second road sealing surface, form the sealing of a kind of " Z " font thus.By two seals, improved sealing to flue gas.
When smoke box is opened, unclamp the bolt between smoke box door and the casing, rely on the rotation of hinge, can outward winding smoke box door, neither destroy sealing surface, can easily the weld seam of smoke pipe, smoke pipe and tube sheet be overhauled and safeguard again.Therefore, the utility model adopts double sealing structure can guarantee sealing in Boiler Furnace, not leak cigarette, and smoke box door has easily and opens when maintenance.Solved the long-standing leakage cigarette of boiler uptake problem.
Description of drawings:
Fig. 1 is the horizontal boiler smoke box Facad structure schematic diagram of the utility model double sealing structure.
Fig. 2 is the I enlarged drawing of Fig. 1.
Among the figure: tube sheet 1 is for the virtual architecture of mounting structure is described.
The specific embodiment:
Referring to Fig. 1～2, the horizontal boiler smoke box of the utility model double sealing structure mainly is made up of casing 2, smoke box door 3, hinge 4, pulling rivet 5, dividing plate 6, graphite asbestos yarn 7, graphite asbestos packing 8, band steel 9, square steel 10, bolt 11, adpting flange 12 and boss 13.Wherein smoke box door 3 is made up of panel, coaming plate, alumina silicate fiber felt, fire clay etc.
Described casing 2 doorways are provided with inside and outside two stage steps face, and first order step surface is a dividing plate 6, and graphite asbestos yarn 7 is fixed on dividing plate 6 outsides by pulling rivet 5.Second level step surface is an adpting flange 12, and graphite asbestos packing 8 is fixed on adpting flange 12 outsides by twice band steel 9.
